GeneralAire’s MAC Air Cleaners are designed to meet today’s high capacity filtration requirements to remove dust mites, mold spores, pollen and dust particles that pollute indoor air. The Opti-Fiber Cartridge Media is easy to replace by simply removing the door and sliding out the old Cartridge Media and sliding in the replacement. The media delivers a high initial efficiency, features fibers which are free of any chemical binders and is hydrophobic (does not absorb moisture), and resists shredding.

Select an air cleaner with dimensions that most closely match your furnace's or air handler's dimensions where the air cleaner will be installed. Most air cleaners attach to a furnace's side, or air handler's bottom or top (depending which is the air inlet). Therefore, select an air cleaner with a length that does not exceed a furnace's depth, or air handler's air-inlet dimensions. (Viewing an upright furnace or air handler from the side, depth is considered the space from left to right.) View online spec sheets for dimensions of furnaces and air handlers sold here. Your order will also include Alpine's exclusive Installation Video on DVD! Watch as a pro tackles the project from start to finish. You'll have all your questions answered as you see how easy it is to install yourself.

Also available is Alpine's Sheet Metal Transition Kit (AHA081). This kit allows you to adapt your existing return air plenum so you can fit in a new air cleaner, if you don't already have the space. Instructional video also shows you how to use the kit to make your air cleaner installation go smoothly. You can view the kit here.

Minimum Efficiency Reporting Value

Rating system created for air filters with a scale that represents the worst case performance of a filter when dealing with particles in the range of 0.3 to 10 micrometers. The scale is from 1-16. The higher the MERV rating the greater the percentage of particles that will be captured.
